Hi all, just start dynamo scripting not long ago. Any help is much appreciated.
I am trying to achieve a series of actions in sequence without opening the actual Revit model.
The actions are:
- Open(detach from central & Audit) model while preserve all workset
- Unload all type of links
- Save as new central to another location with same name
- Relinquish all attributes
I have a bulk of models that required for these actions to be done sequentially, opening 1 model at a time and complete the actions stated above.
I had manage to complete action 1,3 & 4 but could not have any luck with 2. Picture below is the graph that i had come up with from various custom packages and the python script was drafted up by me with multiple reference, awesome learning platform here, but it has a warning of
“Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
The iterator cannot proceed due to changes made to the Element table in Revit’s database (typically, This can be the result of an Element deletion).”
Below is the script
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

clr.AddReference("RevitServices")

from RevitServices.Persistence import DocumentManager

Thanks in advance
